+ <title>Requesting or Suppressing Warnings in Source Files</title>
+ <p>
+ The <c>-dialyzer()</c> attribute can be used for turning off
+ warnings in a module by specifying functions or warning options.
+ For example, to turn off all warnings for the function
+ <c>f/0</c>, include the following line:
+ </p>
+<code type="none">
+-dialyzer({nowarn_function, f/0}).
+</code>
+ <p>To turn off warnings for improper lists, add the following line
+ to the source file:
+ </p>
+<code type="none">
+-dialyzer(no_improper_lists).
+</code>
+ <p>The <c>-dialyzer()</c> attribute is allowed after function
+ declarations. Lists of warning options or functions are allowed:
+ </p>
+<code type="none">
+-dialyzer([{nowarn_function, [f/0]}, no_improper_lists]).
+</code>
+ <p>
+ Warning options can be restricted to functions:
+ </p>
+<code type="none">
+-dialyzer({no_improper_lists, g/0}).
+</code>
+<code type="none">
+-dialyzer({[no_return, no_match], [g/0, h/0]}).
+</code>
+ <p>
+ For help on the warning options use <c>dialyzer -Whelp</c>. The
+ options are also enumerated <seealso
+ marker="#gui/1">below</seealso> (<c>WarnOpts</c>).
+ </p>
+ <note>
+ <p>
+ The <c>-dialyzer()</c> attribute is not checked by the Erlang
+ Compiler, but by the Dialyzer itself.
+ </p>
+ </note>
+ <note>
+ <p>
+ The warning option <c>-Wrace_conditions</c> has no effect when
+ set in source files.
+ </p>
+ </note>
+ <p>
+ The <c>-dialyzer()</c> attribute can also be used for turning on
+ warnings. For instance, if a module has been fixed regarding
+ unmatched returns, adding the line
+ </p>
+<code type="none">
+-dialyzer(unmatched_returns).
+</code>
+ <p>
+ can help in assuring that no new unmatched return warnings are
+ introduced.

+ <p> The translation of Erlang forms to the type
+ representation used by Dialyzer has been improved in

+ <p> Fix a bug that could cause bogus warnings for opaque
+ types. </p> <p>In Erlang/OTP 18 two parameterized types
+ declared in the same module always result in a
+ contradiction (<c>none()</c>) when combined outside of
+ the module where they are declared, unless they have the
+ same number of parameters. </p> <p> The behaviour is
+ different from Erlang/OTP 17 where, for instance,
+ <c>dict:dict()</c> and <c>dict:dict(_, _)</c>, which are
+ both opaque, can be combined outside of the <c>dict</c>
+ module. </p> <p> In Erlang/OTP 18, <c>dict:dict()</c> and
+ <c>dict:dict(_, _)</c> can still be combined outside of
+ the <c>dict</c> module. That has been made possible by
+ not declaring <c>dict:dict()</c> as opaque. </p>

+%%% @doc Type manipulation functions and predefined types.
+%%%
+%%% == Basic types ==
+%%% This module defines all the basic types of the PropEr type system as
+%%% functions. See the <a href="#index">function index</a> for an overview.
+%%%
+%%% Types can be combined in tuples or lists to produce other types. Exact
+%%% values (such as exact numbers, atoms, binaries and strings) can be combined
+%%% with types inside such structures, like in this example of the type of a
+%%% tagged tuple: ``{'result', integer()}''.
+%%%
+%%% When including the PropEr header file, all
+%%% <a href="#index">API functions</a> of this module are automatically
+%%% imported, unless `PROPER_NO_IMPORTS' is defined.
+%%%
+%%% == Customized types ==
+%%% The following operators can be applied to basic types in order to produce
+%%% new ones:
+%%%
+%%% <dl>
+%%% <dt>`?LET(<Xs>, <Xs_type>, <In>)'</dt>
+%%% <dd>To produce an instance of this type, all appearances of the variables
+%%% in `<Xs>' are replaced inside `<In>' by their corresponding values in a
+%%% randomly generated instance of `<Xs_type>'. It's OK for the `<In>' part to
+%%% evaluate to a type - in that case, an instance of the inner type is
+%%% generated recursively.</dd>
+%%% <dt>`?SUCHTHAT(<X>, <Type>, <Condition>)'</dt>
+%%% <dd>This produces a specialization of `<Type>', which only includes those
+%%% members of `<Type>' that satisfy the constraint `<Condition>' - that is,
+%%% those members for which the function `fun(<X>) -> <Condition> end' returns
+%%% `true'. If the constraint is very strict - that is, only a small
+%%% percentage of instances of `<Type>' pass the test - it will take a lot of
+%%% tries for the instance generation subsystem to randomly produce a valid
+%%% instance. This will result in slower testing, and testing may even be
+%%% stopped short, in case the `constraint_tries' limit is reached (see the
+%%% "Options" section in the documentation of the {@link proper} module). If
+%%% this is the case, it would be more appropriate to generate valid instances
+%%% of the specialized type using the `?LET' macro. Also make sure that even
+%%% small instances can satisfy the constraint, since PropEr will only try
+%%% small instances at the start of testing. If this is not possible, you can
+%%% instruct PropEr to start at a larger size, by supplying a suitable value
+%%% for the `start_size' option (see the "Options" section in the
+%%% documentation of the {@link proper} module).</dd>
+%%% <dt>`?SUCHTHATMAYBE(<X>, <Type>, <Condition>)'</dt>
+%%% <dd>Equivalent to the `?SUCHTHAT' macro, but the constraint `<Condition>'
+%%% is considered non-strict: if the `constraint_tries' limit is reached, the
+%%% generator will just return an instance of `<Type>' instead of failing,
+%%% even if that instance doesn't satisfy the constraint.</dd>
+%%% <dt>`?SHRINK(<Generator>, <List_of_alt_gens>)'</dt>
+%%% <dd>This creates a type whose instances are generated by evaluating the
+%%% statement block `<Generator>' (this may evaluate to a type, which will
+%%% then be generated recursively). If an instance of such a type is to be
+%%% shrunk, the generators in `<List_of_alt_gens>' are first run to produce
+%%% hopefully simpler instances of the type. Thus, the generators in the
+%%% second argument should be simpler than the default. The simplest ones
+%%% should be at the front of the list, since those are the generators
+%%% preferred by the shrinking subsystem. Like the main `<Generator>', the
+%%% alternatives may also evaluate to a type, which is generated recursively.
+%%% </dd>
+%%% <dt>`?LETSHRINK(<List_of_variables>, <List_of_types>, <Generator>)'</dt>
+%%% <dd>This is created by combining a `?LET' and a `?SHRINK' macro. Instances
+%%% are generated by applying a randomly generated list of values inside
+%%% `<Generator>' (just like a `?LET', with the added constraint that the
+%%% variables and types must be provided in a list - alternatively,
+%%% `<List_of_types>' may be a list or vector type). When shrinking instances
+%%% of such a type, the sub-instances that were combined to produce it are
+%%% first tried in place of the failing instance.</dd>
+%%% <dt>`?LAZY(<Generator>)'</dt>
+%%% <dd>This construct returns a type whose only purpose is to delay the
+%%% evaluation of `<Generator>' (`<Generator>' can return a type, which will
+%%% be generated recursively). Using this, you can simulate the lazy
+%%% generation of instances:
+%%% ``` stream() -> ?LAZY(frequency([ {1,[]}, {3,[0|stream()]} ])). '''
+%%% The above type produces lists of zeroes with an average length of 3. Note
+%%% that, had we not enclosed the generator with a `?LAZY' macro, the
+%%% evaluation would continue indefinitely, due to the eager evaluation of
+%%% the Erlang language.</dd>
+%%% <dt>`non_empty(<List_or_binary_type>)'</dt>
+%%% <dd>See the documentation for {@link non_empty/1}.</dd>
+%%% <dt>`noshrink(<Type>)'</dt>
+%%% <dd>See the documentation for {@link noshrink/1}.</dd>
+%%% <dt>`default(<Default_value>, <Type>)'</dt>
+%%% <dd>See the documentation for {@link default/2}.</dd>
+%%% <dt>`with_parameter(<Parameter>, <Value>, <Type>)'</dt>
+%%% <dd>See the documentation for {@link with_parameter/3}.</dd>
+%%% <dt>`with_parameters(<Param_value_pairs>, <Type>)'</dt>
+%%% <dd>See the documentation for {@link with_parameters/2}.</dd>
+%%% </dl>
+%%%
+%%% == Size manipulation ==
+%%% The following operators are related to the `size' parameter, which controls
+%%% the maximum size of produced instances. The actual size of a produced
+%%% instance is chosen randomly, but can never exceed the value of the `size'
+%%% parameter at the moment of generation. A more accurate definition is the
+%%% following: the maximum instance of `size S' can never be smaller than the
+%%% maximum instance of `size S-1'. The actual size of an instance is measured
+%%% differently for each type: the actual size of a list is its length, while
+%%% the actual size of a tree may be the number of its internal nodes. Some
+%%% types, e.g. unions, have no notion of size, thus their generation is not
+%%% influenced by the value of `size'. The `size' parameter starts at 1 and
+%%% grows automatically during testing.
+%%%
+%%% <dl>
+%%% <dt>`?SIZED(<S>, <Generator>)'</dt>
+%%% <dd>Creates a new type, whose instances are produced by replacing all
+%%% appearances of the `<S>' parameter inside the statement block
+%%% `<Generator>' with the value of the `size' parameter. It's OK for the
+%%% `<Generator>' to return a type - in that case, an instance of the inner
+%%% type is generated recursively.</dd>
+%%% <dt>`resize(<New_size>, <Type>)'</dt>
+%%% <dd>See the documentation for {@link resize/2}.</dd>
+%%% </dl>

+
+%%% @doc Erlang type system - PropEr type system integration module.
+%%%
+%%% PropEr can parse types expressed in Erlang's type language and convert them
+%%% to its own type format. Such expressions can be used instead of regular type
+%%% constructors in the second argument of `?FORALL's. No extra notation is
+%%% required; PropEr will detect which calls correspond to native types by
+%%% applying a parse transform during compilation. This parse transform is
+%%% automatically applied to any module that includes the `proper.hrl' header
+%%% file. You can disable this feature by compiling your modules with
+%%% `-DPROPER_NO_TRANS'. Note that this will currently also disable the
+%%% automatic exporting of properties.
+%%%
+%%% The use of native types in properties is subject to the following usage
+%%% rules:
+%%% <ul>
+%%% <li>Native types cannot be used outside of `?FORALL's.</li>
+%%% <li>Inside `?FORALL's, native types can be combined with other native
+%%% types, and even with PropEr types, inside tuples and lists (the constructs
+%%% `[...]', `{...}' and `++' are all allowed).</li>
+%%% <li>All other constructs of Erlang's built-in type system (e.g. `|' for
+%%% union, `_' as an alias of `any()', `<<_:_>>' binary type syntax and
+%%% `fun((...) -> ...)' function type syntax) are not allowed in `?FORALL's,
+%%% because they are rejected by the Erlang parser.</li>
+%%% <li>Anything other than a tuple constructor, list constructor, `++'
+%%% application, local or remote call will automatically be considered a
+%%% PropEr type constructor and not be processed further by the parse
+%%% transform.</li>
+%%% <li>Parametric native types are fully supported; of course, they can only
+%%% appear instantiated in a `?FORALL'. The arguments of parametric native
+%%% types are always interpreted as native types.</li>
+%%% <li>Parametric PropEr types, on the other hand, can take any kind of
+%%% argument. You can even mix native and PropEr types in the arguments of a
+%%% PropEr type. For example, assuming that the following declarations are
+%%% present:
+%%% ``` my_proper_type() -> ?LET(...).
+%%% -type my_native_type() :: ... .'''
+%%% Then the following expressions are all legal:
+%%% ``` vector(2, my_native_type())
+%%% function(0, my_native_type())
+%%% union([my_proper_type(), my_native_type()])''' </li>
+%%% <li>Some type constructors can take native types as arguments (but only
+%%% inside `?FORALL's):
+%%% <ul>
+%%% <li>`?SUCHTHAT', `?SUCHTHATMAYBE', `non_empty', `noshrink': these work
+%%% with native types too</li>
+%%% <li>`?LAZY', `?SHRINK', `resize', `?SIZED': these don't work with native
+%%% types</li>
+%%% <li>`?LET', `?LETSHRINK': only the top-level base type can be a native
+%%% type</li>
+%%% </ul></li>
+%%% <li>Native type declarations in the `?FORALL's of a module can reference any
+%%% custom type declared in a `-type' or `-opaque' attribute of the same
+%%% module, as long as no module identifier is used.</li>
+%%% <li>Typed records cannot be referenced inside `?FORALL's using the
+%%% `#rec_name{}' syntax. To use a typed record in a `?FORALL', enclose the
+%%% record in a custom type like so:
+%%% ``` -type rec_name() :: #rec_name{}. '''
+%%% and use the custom type instead.</li>
+%%% <li>`?FORALL's may contain references to self-recursive or mutually
+%%% recursive native types, so long as each type in the hierarchy has a clear
+%%% base case.
+%%% Currently, PropEr requires that the toplevel of any recursive type
+%%% declaration is either a (maybe empty) list or a union containing at least
+%%% one choice that doesn't reference the type directly (it may, however,
+%%% reference any of the types that are mutually recursive with it). This
+%%% means, for example, that some valid recursive type declarations, such as
+%%% this one:
+%%% ``` ?FORALL(..., a(), ...) '''
+%%% where:
+%%% ``` -type a() :: {'a','none' | a()}. '''
+%%% are not accepted by PropEr. However, such types can be rewritten in a way
+%%% that allows PropEr to parse them:
+%%% ``` ?FORALL(..., a(), ...) '''
+%%% where:
+%%% ``` -type a() :: {'a','none'} | {'a',a()}. '''
+%%% This also means that recursive record declarations are not allowed:
+%%% ``` ?FORALL(..., rec(), ...) '''
+%%% where:
+%%% ``` -type rec() :: #rec{}.
+%%% -record(rec, {a = 0 :: integer(), b = 'nil' :: 'nil' | #rec{}}). '''
+%%% A little rewritting can usually remedy this problem as well:
+%%% ``` ?FORALL(..., rec(), ...) '''
+%%% where:
+%%% ``` -type rec() :: #rec{b :: 'nil'} | #rec{b :: rec()}.
+%%% -record(rec, {a = 0 :: integer(), b = 'nil' :: 'nil' | #rec{}}). '''
+%%% </li>
+%%% <li>Remote types may be referenced in a `?FORALL', so long as they are
+%%% exported from the remote module. Currently, PropEr requires that any
+%%% remote modules whose types are directly referenced from within properties
+%%% are present in the code path at compile time, either compiled with
+%%% `debug_info' enabled or in source form. If PropEr cannot find a remote
+%%% module at all, finds only a compiled object file with no debug
+%%% information or fails to compile the source file, all calls to that module
+%%% will automatically be considered calls to PropEr type constructors.</li>
+%%% <li>For native types to be translated correctly, both the module that
+%%% contains the `?FORALL' declaration as well as any module that contains
+%%% the declaration of a type referenced (directly or indirectly) from inside
+%%% a `?FORALL' must be present in the code path at runtime, either compiled
+%%% with `debug_info' enabled or in source form.</li>
+%%% <li>Local types with the same name as an auto-imported BIF are not accepted
+%%% by PropEr, unless the BIF in question has been declared in a
+%%% `no_auto_import' option.</li>
+%%% <li>When an expression can be interpreted both as a PropEr type and as a
+%%% native type, the former takes precedence. This means that a function
+%%% `foo()' will shadow a type `foo()' if they are both present in the module.
+%%% The same rule applies to remote functions and types as well.</li>
+%%% <li>The above may cause some confusion when list syntax is used:
+%%% <ul>
+%%% <li>The expression `[integer()]' can be interpreted both ways, so the
+%%% PropEr way applies. Therefore, instances of this type will always be
+%%% lists of length 1, not arbitrary integer lists, as would be expected
+%%% when interpreting the expression as a native type.</li>
+%%% <li>Assuming that a custom type foo/1 has been declared, the expression
+%%% `foo([integer()])' can only be interpreted as a native type declaration,
+%%% which means that the generic type of integer lists will be passed to
+%%% `foo/1'.</li>
+%%% </ul></li>
+%%% <li>Currently, PropEr does not detect the following mistakes:
+%%% <ul>
+%%% <li>inline record-field specializations that reference non-existent
+%%% fields</li>
+%%% <li>type parameters that are not present in the RHS of a `-type'
+%%% declaration</li>
+%%% <li>using `_' as a type variable in the LHS of a `-type' declaration</li>
+%%% <li>using the same variable in more than one position in the LHS of a
+%%% `-type' declaration</li>
+%%% </ul>
+%%% </li>
+%%% </ul>
+%%%
+%%% You can use <a href="#index">these</a> functions to try out the type
+%%% translation subsystem.
+%%%
+%%% CAUTION: These functions should never be used inside properties. They are
+%%% meant for demonstration purposes only.

+%%% @doc Type manipulation functions and predefined types.
+%%%
+%%% == Basic types ==
+%%% This module defines all the basic types of the PropEr type system as
+%%% functions. See the <a href="#index">function index</a> for an overview.
+%%%
+%%% Types can be combined in tuples or lists to produce other types. Exact
+%%% values (such as exact numbers, atoms, binaries and strings) can be combined
+%%% with types inside such structures, like in this example of the type of a
+%%% tagged tuple: ``{'result', integer()}''.
+%%%
+%%% When including the PropEr header file, all
+%%% <a href="#index">API functions</a> of this module are automatically
+%%% imported, unless `PROPER_NO_IMPORTS' is defined.
+%%%
+%%% == Customized types ==
+%%% The following operators can be applied to basic types in order to produce
+%%% new ones:
+%%%
+%%% <dl>
+%%% <dt>`?LET(<Xs>, <Xs_type>, <In>)'</dt>
+%%% <dd>To produce an instance of this type, all appearances of the variables
+%%% in `<Xs>' are replaced inside `<In>' by their corresponding values in a
+%%% randomly generated instance of `<Xs_type>'. It's OK for the `<In>' part to
+%%% evaluate to a type - in that case, an instance of the inner type is
+%%% generated recursively.</dd>
+%%% <dt>`?SUCHTHAT(<X>, <Type>, <Condition>)'</dt>
+%%% <dd>This produces a specialization of `<Type>', which only includes those
+%%% members of `<Type>' that satisfy the constraint `<Condition>' - that is,
+%%% those members for which the function `fun(<X>) -> <Condition> end' returns
+%%% `true'. If the constraint is very strict - that is, only a small
+%%% percentage of instances of `<Type>' pass the test - it will take a lot of
+%%% tries for the instance generation subsystem to randomly produce a valid
+%%% instance. This will result in slower testing, and testing may even be
+%%% stopped short, in case the `constraint_tries' limit is reached (see the
+%%% "Options" section in the documentation of the {@link proper} module). If
+%%% this is the case, it would be more appropriate to generate valid instances
+%%% of the specialized type using the `?LET' macro. Also make sure that even
+%%% small instances can satisfy the constraint, since PropEr will only try
+%%% small instances at the start of testing. If this is not possible, you can
+%%% instruct PropEr to start at a larger size, by supplying a suitable value
+%%% for the `start_size' option (see the "Options" section in the
+%%% documentation of the {@link proper} module).</dd>
+%%% <dt>`?SUCHTHATMAYBE(<X>, <Type>, <Condition>)'</dt>
+%%% <dd>Equivalent to the `?SUCHTHAT' macro, but the constraint `<Condition>'
+%%% is considered non-strict: if the `constraint_tries' limit is reached, the
+%%% generator will just return an instance of `<Type>' instead of failing,
+%%% even if that instance doesn't satisfy the constraint.</dd>
+%%% <dt>`?SHRINK(<Generator>, <List_of_alt_gens>)'</dt>
+%%% <dd>This creates a type whose instances are generated by evaluating the
+%%% statement block `<Generator>' (this may evaluate to a type, which will
+%%% then be generated recursively). If an instance of such a type is to be
+%%% shrunk, the generators in `<List_of_alt_gens>' are first run to produce
+%%% hopefully simpler instances of the type. Thus, the generators in the
+%%% second argument should be simpler than the default. The simplest ones
+%%% should be at the front of the list, since those are the generators
+%%% preferred by the shrinking subsystem. Like the main `<Generator>', the
+%%% alternatives may also evaluate to a type, which is generated recursively.
+%%% </dd>
+%%% <dt>`?LETSHRINK(<List_of_variables>, <List_of_types>, <Generator>)'</dt>
+%%% <dd>This is created by combining a `?LET' and a `?SHRINK' macro. Instances
+%%% are generated by applying a randomly generated list of values inside
+%%% `<Generator>' (just like a `?LET', with the added constraint that the
+%%% variables and types must be provided in a list - alternatively,
+%%% `<List_of_types>' may be a list or vector type). When shrinking instances
+%%% of such a type, the sub-instances that were combined to produce it are
+%%% first tried in place of the failing instance.</dd>
+%%% <dt>`?LAZY(<Generator>)'</dt>
+%%% <dd>This construct returns a type whose only purpose is to delay the
+%%% evaluation of `<Generator>' (`<Generator>' can return a type, which will
+%%% be generated recursively). Using this, you can simulate the lazy
+%%% generation of instances:
+%%% ``` stream() -> ?LAZY(frequency([ {1,[]}, {3,[0|stream()]} ])). '''
+%%% The above type produces lists of zeroes with an average length of 3. Note
+%%% that, had we not enclosed the generator with a `?LAZY' macro, the
+%%% evaluation would continue indefinitely, due to the eager evaluation of
+%%% the Erlang language.</dd>
+%%% <dt>`non_empty(<List_or_binary_type>)'</dt>
+%%% <dd>See the documentation for {@link non_empty/1}.</dd>
+%%% <dt>`noshrink(<Type>)'</dt>
+%%% <dd>See the documentation for {@link noshrink/1}.</dd>
+%%% <dt>`default(<Default_value>, <Type>)'</dt>
+%%% <dd>See the documentation for {@link default/2}.</dd>
+%%% <dt>`with_parameter(<Parameter>, <Value>, <Type>)'</dt>
+%%% <dd>See the documentation for {@link with_parameter/3}.</dd>
+%%% <dt>`with_parameters(<Param_value_pairs>, <Type>)'</dt>
+%%% <dd>See the documentation for {@link with_parameters/2}.</dd>
+%%% </dl>
+%%%
+%%% == Size manipulation ==
+%%% The following operators are related to the `size' parameter, which controls
+%%% the maximum size of produced instances. The actual size of a produced
+%%% instance is chosen randomly, but can never exceed the value of the `size'
+%%% parameter at the moment of generation. A more accurate definition is the
+%%% following: the maximum instance of `size S' can never be smaller than the
+%%% maximum instance of `size S-1'. The actual size of an instance is measured
+%%% differently for each type: the actual size of a list is its length, while
+%%% the actual size of a tree may be the number of its internal nodes. Some
+%%% types, e.g. unions, have no notion of size, thus their generation is not
+%%% influenced by the value of `size'. The `size' parameter starts at 1 and
+%%% grows automatically during testing.
+%%%
+%%% <dl>
+%%% <dt>`?SIZED(<S>, <Generator>)'</dt>
+%%% <dd>Creates a new type, whose instances are produced by replacing all
+%%% appearances of the `<S>' parameter inside the statement block
+%%% `<Generator>' with the value of the `size' parameter. It's OK for the
+%%% `<Generator>' to return a type - in that case, an instance of the inner
+%%% type is generated recursively.</dd>
+%%% <dt>`resize(<New_size>, <Type>)'</dt>
+%%% <dd>See the documentation for {@link resize/2}.</dd>
+%%% </dl>

+
+%%% @doc Erlang type system - PropEr type system integration module.
+%%%
+%%% PropEr can parse types expressed in Erlang's type language and convert them
+%%% to its own type format. Such expressions can be used instead of regular type
+%%% constructors in the second argument of `?FORALL's. No extra notation is
+%%% required; PropEr will detect which calls correspond to native types by
+%%% applying a parse transform during compilation. This parse transform is
+%%% automatically applied to any module that includes the `proper.hrl' header
+%%% file. You can disable this feature by compiling your modules with
+%%% `-DPROPER_NO_TRANS'. Note that this will currently also disable the
+%%% automatic exporting of properties.
+%%%
+%%% The use of native types in properties is subject to the following usage
+%%% rules:
+%%% <ul>
+%%% <li>Native types cannot be used outside of `?FORALL's.</li>
+%%% <li>Inside `?FORALL's, native types can be combined with other native
+%%% types, and even with PropEr types, inside tuples and lists (the constructs
+%%% `[...]', `{...}' and `++' are all allowed).</li>
+%%% <li>All other constructs of Erlang's built-in type system (e.g. `|' for
+%%% union, `_' as an alias of `any()', `<<_:_>>' binary type syntax and
+%%% `fun((...) -> ...)' function type syntax) are not allowed in `?FORALL's,
+%%% because they are rejected by the Erlang parser.</li>
+%%% <li>Anything other than a tuple constructor, list constructor, `++'
+%%% application, local or remote call will automatically be considered a
+%%% PropEr type constructor and not be processed further by the parse
+%%% transform.</li>
+%%% <li>Parametric native types are fully supported; of course, they can only
+%%% appear instantiated in a `?FORALL'. The arguments of parametric native
+%%% types are always interpreted as native types.</li>
+%%% <li>Parametric PropEr types, on the other hand, can take any kind of
+%%% argument. You can even mix native and PropEr types in the arguments of a
+%%% PropEr type. For example, assuming that the following declarations are
+%%% present:
+%%% ``` my_proper_type() -> ?LET(...).
+%%% -type my_native_type() :: ... .'''
+%%% Then the following expressions are all legal:
+%%% ``` vector(2, my_native_type())
+%%% function(0, my_native_type())
+%%% union([my_proper_type(), my_native_type()])''' </li>
+%%% <li>Some type constructors can take native types as arguments (but only
+%%% inside `?FORALL's):
+%%% <ul>
+%%% <li>`?SUCHTHAT', `?SUCHTHATMAYBE', `non_empty', `noshrink': these work
+%%% with native types too</li>
+%%% <li>`?LAZY', `?SHRINK', `resize', `?SIZED': these don't work with native
+%%% types</li>
+%%% <li>`?LET', `?LETSHRINK': only the top-level base type can be a native
+%%% type</li>
+%%% </ul></li>
+%%% <li>Native type declarations in the `?FORALL's of a module can reference any
+%%% custom type declared in a `-type' or `-opaque' attribute of the same
+%%% module, as long as no module identifier is used.</li>
+%%% <li>Typed records cannot be referenced inside `?FORALL's using the
+%%% `#rec_name{}' syntax. To use a typed record in a `?FORALL', enclose the
+%%% record in a custom type like so:
+%%% ``` -type rec_name() :: #rec_name{}. '''
+%%% and use the custom type instead.</li>
+%%% <li>`?FORALL's may contain references to self-recursive or mutually
+%%% recursive native types, so long as each type in the hierarchy has a clear
+%%% base case.
+%%% Currently, PropEr requires that the toplevel of any recursive type
+%%% declaration is either a (maybe empty) list or a union containing at least
+%%% one choice that doesn't reference the type directly (it may, however,
+%%% reference any of the types that are mutually recursive with it). This
+%%% means, for example, that some valid recursive type declarations, such as
+%%% this one:
+%%% ``` ?FORALL(..., a(), ...) '''
+%%% where:
+%%% ``` -type a() :: {'a','none' | a()}. '''
+%%% are not accepted by PropEr. However, such types can be rewritten in a way
+%%% that allows PropEr to parse them:
+%%% ``` ?FORALL(..., a(), ...) '''
+%%% where:
+%%% ``` -type a() :: {'a','none'} | {'a',a()}. '''
+%%% This also means that recursive record declarations are not allowed:
+%%% ``` ?FORALL(..., rec(), ...) '''
+%%% where:
+%%% ``` -type rec() :: #rec{}.
+%%% -record(rec, {a = 0 :: integer(), b = 'nil' :: 'nil' | #rec{}}). '''
+%%% A little rewritting can usually remedy this problem as well:
+%%% ``` ?FORALL(..., rec(), ...) '''
+%%% where:
+%%% ``` -type rec() :: #rec{b :: 'nil'} | #rec{b :: rec()}.
+%%% -record(rec, {a = 0 :: integer(), b = 'nil' :: 'nil' | #rec{}}). '''
+%%% </li>
+%%% <li>Remote types may be referenced in a `?FORALL', so long as they are
+%%% exported from the remote module. Currently, PropEr requires that any
+%%% remote modules whose types are directly referenced from within properties
+%%% are present in the code path at compile time, either compiled with
+%%% `debug_info' enabled or in source form. If PropEr cannot find a remote
+%%% module at all, finds only a compiled object file with no debug
+%%% information or fails to compile the source file, all calls to that module
+%%% will automatically be considered calls to PropEr type constructors.</li>
+%%% <li>For native types to be translated correctly, both the module that
+%%% contains the `?FORALL' declaration as well as any module that contains
+%%% the declaration of a type referenced (directly or indirectly) from inside
+%%% a `?FORALL' must be present in the code path at runtime, either compiled
+%%% with `debug_info' enabled or in source form.</li>
+%%% <li>Local types with the same name as an auto-imported BIF are not accepted
+%%% by PropEr, unless the BIF in question has been declared in a
+%%% `no_auto_import' option.</li>
+%%% <li>When an expression can be interpreted both as a PropEr type and as a
+%%% native type, the former takes precedence. This means that a function
+%%% `foo()' will shadow a type `foo()' if they are both present in the module.
+%%% The same rule applies to remote functions and types as well.</li>
+%%% <li>The above may cause some confusion when list syntax is used:
+%%% <ul>
+%%% <li>The expression `[integer()]' can be interpreted both ways, so the
+%%% PropEr way applies. Therefore, instances of this type will always be
+%%% lists of length 1, not arbitrary integer lists, as would be expected
+%%% when interpreting the expression as a native type.</li>
+%%% <li>Assuming that a custom type foo/1 has been declared, the expression
+%%% `foo([integer()])' can only be interpreted as a native type declaration,
+%%% which means that the generic type of integer lists will be passed to
+%%% `foo/1'.</li>
+%%% </ul></li>
+%%% <li>Currently, PropEr does not detect the following mistakes:
+%%% <ul>
+%%% <li>inline record-field specializations that reference non-existent
+%%% fields</li>
+%%% <li>type parameters that are not present in the RHS of a `-type'
+%%% declaration</li>
+%%% <li>using `_' as a type variable in the LHS of a `-type' declaration</li>
+%%% <li>using the same variable in more than one position in the LHS of a
+%%% `-type' declaration</li>
+%%% </ul>
+%%% </li>
+%%% </ul>
+%%%
+%%% You can use <a href="#index">these</a> functions to try out the type
+%%% translation subsystem.

+%%% CAUTION: These functions should never be used inside properties. They are
